Abstract: Two tobacco streams are made simultaneously by feeding a main flow of tobacco particles upwardly through a suction duct which terminates beneath two parallel foraminous belt conveyors. The sidewalls of the duct have alternating wedge-like ramps which divide the ascending main flow into plural first and second flows in such a way that the first flows advance from one of the sidewalls toward the other sidewall and the second flows advance from the other sidewall toward the one sidewall. In addition, the sidewalls and their ramps define several passageways for unimpeded ascent of numerous relatively small third flows of tobacco particles directly against the convex underside of a partition which is located in the duct between the two conveyors. The partition breaks up each third flow into two equal partial flows and causes each partial flow to rise toward a different foraminous conveyor.
Abstract: The present invention relates to a mid-line clamp assembly for use in a posterior spinal system including components designed to be affixed to the spinal column of a person to correct for various lateral and sagittal deformities. The clamp assembly includes inferior and superior clamp halves slidably interconnected with one another. Each clamp half has a body portion and a shoe connected to the body portion. Each clamp half has a stud connected to the body portion. The studs are connectable to other members incorporated in this spinal system for fixing the position of the clamp halves with respect to each other. The clamps are used in conjunction with the spinal system which also includes a pair of smooth surfaced rods mounted in spaced relation to one another on the spinal column in conjunction with various fixation devices such as the clamps with hook bodies, hooks, screws with hook bodies and couplers.

Abstract: A relatively wide first layer of tobacco particles is broken up into several narrower second and several narrower third layers. The second layers are converted into a first tobacco filler stream which is trimmed to form a rod-like filler ready to be draped into a web of cigarette paper, and the third layers are converted into a second tobacco filler stream which is ready to be trimmed to form a rod-like filler ready to be draped into a web of cigarette paper. The tobacco layers are caused to advance along and closely follow concave sides of guide surfaces and are propelled along the respective surfaces by streams of compressed air. Subdivision of the first layer into several second and several third layers reduces the likelihood of unmixing or dehomogenization of the mixtures of tobacco particles which are about to be converted into plural tobacco filler streams.

Abstract: A method of manufacturing filter-tipped cigarettes whereby series of first and second double cigarette portions, produced by transversely cutting two continuous cigarette rods traveling axially at substantially constant speed, are fed by respective transfer members into respective seats on respective first and second receiving rollers.The first double portions are then fed into respective seats on a third transfer roller and subsequently into alternate seats on a fourth transfer roller, the vacant seats of which receive the second double portions supplied by the second transfer roller. The first and second double portions on the fourth transfer roller are cut transversely to produce, on the fourth roller, successive pairs of aligned single portions, which are parted axially, connected via the interposition of a double filter, and then cut into cigarettes by cutting the double filter.
Abstract: A reading method for reading text whereby the reader listens to a cyclic stereophonic sound pattern while reading text. The cyclic stereophonic sound pattern paces the reader's eye movement over the text. A decrease in the pitch of the stereophonic sound pattern reduces reader stress due to learning to read more quickly. The invention also includes reading improvement apparatus used in the practice of this method.
Abstract: A mounting arrangement for a tooth in an artificial dental jaw model, especially in an artificial denture skull, and which is utilized for teaching and practice purposes. The tooth which is to be exchanged or replaced can be pulled out with an ordinary pair of extracting pliers and in an imitation of an actual extracting procedure, and the new tooth can be inserted with the application of a forcible or strong finger pressure.
